Serial No.254,657. V

This invention relates to what is known as a safety closure for receptacles adapted to contain volatile inflammable liquids such as gasoline, alcohol and the like and has for its object to provide a springheld-closure asso ciated with a hand lever. which is in turn associated with the bail or handleof the receptacle so as to be grasped and operated to permit flow from the receptacle atthe same time that the latter is lifted preparatory to tilting the same to cause flow ofliquid therefrom, the present invention being directed to specific improvements in the mechanism which renders it eflicient. to maintain the receptacle normally sealed and the sealing mechanism easily operable to permit discharge of liquid. 1

Receptacles of the class to which the invention relates are made in different sizesand as between the smaller and larger sizes the main difference lies in the diameter of the receptacle body and in the specific type and location of the bail or handle thereof. It is desirable for reasons of cost economy in the manufacture of receptacles differing in diameter to employ the same size spout and closure mechanism and an important feature of the present invention consists in so form ing the tops of receptacles of different diameters as topermit the; spouts or nozzles and the closuresthereof to be interchangeably associated with the same thus necessitating only a change in the operating lever to accommodate the latter to such various sizes of said receptacles. Y

The invention is fully illustrated in the accompanying drawings wherein:

Fig. 1 is aside elevation of a receptacle and closure mechanism therefor constructed in accordance with=my invention. Fig. 2 is a central vertical section of same on the line 2-2 of Fig. 3. V Fig. 3 is a plan section on the line 3-.3 of Fig.

Fig. 4 is a front elevation of the same.

F ig. 5 is a side elevation of a receptacle equipped with a modified form of closure mechanism.

The receptacle body 1 is usually and preferably cylindrical and varies in length for various capacities from'a given minimum to a given maximum." Sizes larger than the latter are of larger diameter and again varied in length forvarious capacities. This scheme permits the manufacturer to produce a large line of difi'erent sizes of receptacles at the smallest cost for dies to form the top and bottom walls, the former being dished and presenting its convex surface outwardly. The top wall is provided with a discharge opening which is disposed eccentrically thereof and is bordered by the flange 3 of the discharge spout or nozzle 4 which, while cylindrical, is passed through the discharge openmg and 1s thenflared to lie in close contact with the'inner faceof the head 2 to which it isthen soldered to provide a fluid tightj oint. The body of the nozzle 4 is thus disposed anglularly of the vertical axis of the receptac e.

Rigid with the spout or nozzle 4 is a ver tically disposed U-shaped memberG which is provided along its lower end with flanges 7 which are secured bymeans of rivets, or

otherwise, to'the top wall 2-or top wall of the boss 5 of the receptacle. The handle or bail 8 of the receptacle is equipped with a vertical end portion 9 the lower end portion of which is suitably secured'to the upper rear corner portion of the member 6, the other endportion of saidhandle. or bail 8 being suitably rigidly secured to the receptacle body 1. Said bail or handle is usually a fiat metal structure consisting preferably of light'fsheet metal having wires enclosed in its side edge portions. H

Pivotally secured to the upper end portion of the member 6 between the side flanges thereof isa' U-shapedbar 11 to which the closure cap 12 for the spout or nozzle l is discharge nozzle mounted eccentrically of the longitudinal axis of the receptacle body upon the top wall thereof, a bail 0r handle secured at one end to the receptacle body and extending over the top wall thereof and downwardly to a point approximately in alignment with the longitudinal axis of the body behind said nozzle, a hand lever disposed mainly between the handle and the receptacle top and pivotally secured at one end to the receptacle, a closure cap for the nozzle having pivotal and sliding connection with said lever for movement to and from the nozzle and for movement relatively to said lever to cause said cap to adjust itself to firmly seat upon the nozzle, and a spring engaged with said lever for normally holdingthe same at the limit of its movement whereat the cap is seated, there being a slot in said handle through which the non-pivoted end portion of said lever projects. I

2. A receptacle provided with a handle overhanging the top wall thereof from about its center to its periphery, the portion of said handle at the center of said top wall being provided with a longitudinal slot, a discharge nozzle mounted on said top wall in alignment with a vertical plane intersecting the handle between its side edges, a hand lever pivotally secured at one end to the receptacle adjacent the peripheral edge of its top wall and at its other end portion projecting through said slot and operating in said plane, a closure cap for said nozzle having pivotal and sliding connection with said lever for opening and closing movement by the latter and for movement relatively to said lever for causing self-seating of said cap on said nozzle, and a spring operatively associated with said lever for maintaining said cap normally seated.

3. In a receptacle, a discharge nozzle equipped at one side with a rigid longitudinal flange, a closure cap seating on said nozzle, a flange rigid with said cap and provided between its ends with a longitudinal slot, a pin pivotally connecting said flanges at a point spaced from said cap, there being a slot in one of said flanges extending sub-- stantially perpendicularly of the slot in said flange of said cap through which said pin passes, a hand lever and a spring therefor, said lever engaging at one end in the longitudinal slot in said flange of said cap and pivotally secured at its other end to the receptacle for maintaining said cap normally seated on said nozzle and coacting with said pivot pin and the slot through which the latter passes to firmly seat said cap.

4:. Areceptacle equipped with a discharge nozzle projecting from its top wall and disposed in spaced relation to the vertical axis of the receptacle, a handle for said receptacle having a vertical arm portion secured to the said nozzle and provided with a longitudinal being bent and its extremeend secured tolthe peripheral wall of the receptacle at. a point diametrically opposite the said nozzle, a closurecap for the latter, a lever, a spring maintainlng said lever normally bearmg upon said cap at substantially its center and loosely engaged with said capto cause said cap to adjust itself to scaling position: on said nozzle, said lever extending through the slot in the vertical arm of said handle for guidance thereby and pivotally. connected at one end with the receptacle body at a point adjacent to the top thereof and diametrically opposed to the nozzle, the middle portion of said lever being normally spaced from the middle portion of said handle.

5. A receptacle equipped with a discharge cap to adjust itself to sealing position on said nozzle, the middle portion of said lever spaced from and lying below the middle portion of the handle with respect to the top wall of the receptacle.

6. A receptacle equipped with a discharge nozzle, a closure cap for sealing the latter, a

handle for said receptacle overhanging the top wall thereof and provided in the over hanging portion witha guide slot, a springheld lever pivotally secured at one end to the a receptacle and overhanging the top thereof and engaged between its ends in said slot, a spring engaged with said lever, a diametric flange on said cap provided with a longitudinal slot, the other end of said lever slidably' engaged in said slot and normally exerting pressure on said cap responsively to said spring at substantially the center of said cap,

means loosely pivotally associating said cap with said nozzle for causing the cap to adjust itself to scaling position on said nozzle under the influence of the pressure of said lever, the middle portion of said lever spaced from and lying below the middle portion of the handle with respect to the top wall of the receptacle.
